Home made DIY Grey water system water recycling.

Step 11 Update fine tuning

Hi

I have been using this grey water system for about 6 months now.
In this time I have had 1 or 2 small problems that I have had to sort out.

The first one is, I have had 2 switches fail. I have put this down to the switches not being able to cope with the current drawn by the relays so I have made a simple transistor circuit to reduce the current going through the switches this has also enabled me to use just 1 relay.

see attached circuit diagram.

the second problem has been when the weather gets hot there is a bit of a smell from the grey water stored in the tank in the loft.

I have calculated that the tank in the loft is holding to much water for to long.
It is holding enough water for 5 days. so I am replacing the tank in the loft with a smaller tank which will hold enough water for 1-2 days. then more of the water will be stored in the tubes outside. and the water will be recycled sooner. and won't be sitting around getting smelly.

I did think about doing it that way. but its good to have a storage tank in case. the toilet is used more. and the tubes outside get emptied. or if I have any problems with the system. a storage tank gives me a bit more lee way.

Couldn't you just skip the attic tank and have the pump piped directly to the toilet? A small pressure tank and pressure switch would be necessary, but there would be no exposed water inside to stink up the place except in the toilet.
